Earlier in 2025, Chinese solar manufacturer Longi announced it had built the world's most efficient solar cell. The hybrid interdigitated back-contact (HIBC) cell achieved 27.81% efficiency, which was ...

The government’s domestic sourcing mandate is aimed at reducing dependence on imports. But it may also squeeze smaller ...

The ALMM mandate now requires government-backed and large-scale solar projects to use locally made cells. Here's what it ...

Light can hit a lead halide perovskite crystal that is anything but pristine and still end up as useful electric current. That mismatch has bothered solar researchers for more than a decade. Silicon ...

In a study published in Nature, researchers at Linköping University have developed a method to recycle all parts of a solar cell repeatedly without environmentally hazardous solvents. The recycled ...

In a new scientific paper, the Chinese solar manufacturer explained that the 27.81%-efficient hybrid interdigitated back-contact cell it unveiled in April is based on passivated tunneling contacts and ...

Improving solar cell performance with narrower contact fingers Fraunhofer ISE researchers have developed a new metallization process that can produce ultra-fine line contacts for solar cells. The ...

Flexible solar panels are lightweight, portable and useful for curved surfaces, but they are not right for every setup. Here’s how they compare with standard panels ...

Starting June 1 this year, all new net-metering and open-access solar power projects will be required to source solar PV ...
